Which is thicker 5w30 or 10w40?
5w30 is less viscous while 10w40 is more viscous.
The 5w30 has a viscosity of 30 at high temperature while a 10w40 has a 40 viscosity at high temperatures.
When at high temperatures, the 5w30 oil becomes thinner than the 10w40 oil since 30 is lower as compared to 40..
What happens if you mix car oil?
Mixing Motor Oil According to Mobil Oil, it should be fine to mix oils. This manufacturer states it would be unlikely anything bad would happen, such as a gel-forming from an interaction of the chemicals (a common fear), because the oils are compatible with each other.
What happens if I put 5w20 instead of 5w30?
It won’t damage your engine, just switch back to 5w30 next oil change. The high number indicates thickness when warm, You may burn some oil before the next change but I would say let it go.
What happens if you use 10w30 instead of 5w30?
10w30 is thicker then 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.
Does 10w40 hurt 5w30 engine?
Your vehicle does not use 5W-30 oil. The recommended oil viscosity for your vehicle, according to Kia documentation, is 10W-40. If you drive the vehicle in exceptionally cold weather, well below 32 degrees, you can use 5W-30 oil but even 10W-40 is still perfectly OK to use if outdoor temperatures are below freezing.
What is the difference between cheap and expensive engine oil?
Originally Answered: Is there a big difference in quality between more expensive brands of oil like Mobile 1 and cheaper brands of oil? Yes, absolutely. 80% or more of the cost of the finished oil is due to the additive package in the base oil. The cheaper it is the lower quality or fewer additives are in the oil.
Which is better 5w30 or 10w30?
5w30 is used for light-duty engines while 10w30 is used for engines which carry heavier loads. 10w30 provides sealing action in the engine due to the fact that it is thicker than 5w30 engine oil. Thinner at lower temperatures. Thicker at lower temperatures.
Can you mix different brands of synthetic motor oil?
Yes, you can safely mix one brand of oil (e.g. Mobil 1) with a different brand (e.g. AMSOIL) or conventional oil with synthetic oil (in fact, that’s what a synthetic blend is). Most synthetics today are fully compatible with conventional oils and can safely be mixed.
Does oil brand make a difference?
Basically, while the oils do the same thing, the various brands have differing detergents and additives in differing amounts. you will often, but not always, get what you pay for in regards to engine oil. And the nicer ones typically just last longer without as much grunk in them.
Is it OK to put different oil in your car?
The brand of motor oil matters little, but its viscosity grade (10W-30, for example) is important. Use only what the owner’s manual specifies. Using the wrong oil can lead to reduced lubrication and shorter engine life. If the manual says to use synthetic oil, do so.
Can you switch from regular oil to synthetic?
This is one of the most persistent myths about synthetic oil—and completely untrue. You can switch back and forth at any time. In fact, synthetic blends are simply a mixture of synthetic and conventional oils.
Can you mix 5w30 and 10w40?
As posted above, mixing 5w30 with 10w40 will give you an oil that performs somewhat better in the cold than 10w40, but less good cold than 5w30, and that has a viscosity a bit higher than 5w30 but a bit lower than 10w40.
What happens if I use 0w20 instead of 5w30?
0w-20 is simply a different viscosity of oil. It won’t be an advantage to your engine if your manufacturer suggests you use 5w-30 and may indeed be a detriment to your engine. … I would suggest using a viscosity for your engine that your manufacturer recommends. You can find that recommendation in your owner’s manual.
Does brand of oil matter?

MYTH: When motor oil becomes dark, that means it’s time to change it.
Can you mix 5w30 and 10w30?
Yes, if topping up. If your oil must be topped up, then you are burning oil already, so the difference won’t cause more damage than is already there. 5W30 and 10W30 are essentially the same at operating temperature. It is only for cold weather starting that the performance will be different.
When should I use 10w40 oil?
When to Use 10w30 vs 10w40 Using 10w30 oil in cold weather will help reduce excessive oil temperatures and drag as the engine warms up. Using 10w40 oil in the summer will help the oil stick to internal components in high temperatures, avoiding the wear and tear from metal-to-metal contact between moving parts.
Is Castrol oil better than Valvoline?
Castrol. Based on the VOAs posted of GF3 oils, And Valvoline UOAs that I’ve seen haven’t been all that impressive. Castrol, on the other hand, consistenly shows good UOAs. … If your car and your driving habits don’t demand the extra protection a synthetic oil delivers, you can save money by using a conventional oil.
